Introduction
Overview
The MS2601 is a portable, hand-held professional meter
that measures AC/DC voltage, AC/DC current, resistance,
capacitance, diodes, continuity, frequency, duty cycle,
temperature and non-contact voltage. This meter is easy
to use with one hand, suitable for professional users or
amateurs, and ideal for school or home use.
Precautions:
5. Make sure to set the meter to the correct functions and
measuring range before taking measurement.
6.Do not use the meter on a circuit where the measuring
range is over the capable range specified in the user’s
manual.
7. Do not touch the tips of the test leads when performing
measurement.
8. If the measurement is above 60V DC or 30V AC, make
sure to keep fingers behind the barrier and finger guards.
9. Do not use the meter on a circuit if the voltage is above
600V.
10. In manual mode, if the value to be measured is
unknown, start the meter in the maximum range and
then adjust accordingly.
11. Remove the leads from the circuit first before switching
between functions.
12. Disconnect power and discharge all capacitors before
measuring resistance, capacitance, continuity or diodes.
13. Do not measure capacitance before the capacitors
are discharged.
14. Do not operate the meter near explosive gas, vapor
or dust.
15. Stop using the meter if the meter or test leads appear
damaged or do not function properly.
16. Do not use the meter unless the battery case is securely
fastened to the back of the meter.
17. Do not expose the meter to direct sunlight, heat, or
moisture.
Users must follow standard safety instructions while
using the meter:
1. Once the meter is out of the package, check for any
damage to the meter before using.
2. Double check the meter to make sure all the
components are in good condition.
3. Check the test leads before operation. Check the test
leads for damage to the insulation or wires before use.
4. Use the original test leads included in the package for
best performance and safety. If necessary, use
compatible leads with same specifications as the
originals.
WARNING
The special attention should be paid when using the
meter because the improper usage may cause electric
shock and damage the meter .The safety measures in
common safety regulations and operating instruction
should be complied with when using. In order to make
fully use of its functions and ensure safe operations

Using the Meter
Display Hold
During measurement, press / to hold the current
reading on the display. Press again to release the hold.
Manual Mode
• The default range in voltage and resistance modes is
auto. To switch to manual range, press “RAN” and
the display switches to manual mode. Each press of the
button increases the range and returns to the lowest
range when pressed in the highest range.
• Hold “RAN” to switch back to auto-range.
Note:
In current mode, manual is only mode available.In
frequency and capacitance modes, only auto-range is
available.
Switching Between Functions
• When the meter is in voltage mode, press “FUNC” to
switch between DC and AC voltage.
• When the meter is in resistance/continuity/capacitance/
diode mode, press “FUNC” to switch between them.
• When the meter is in temperature mode, press “FUNC”
to switch between Fahrenheit and Celsius units.
Backlight and worklight
• Hold to turn on the display backlight; the backlight
will stay on for 15 seconds before it automatically turns
off.
• To turn off the backlight manually, hold again.
• When the meter is in current mode, turning on the
backlight will also activate the worklight, making it easier
to use the clamp in dark areas.
/
/
Note:
• The meter uses an LED for a backlight; even though the
backlight is set to turn off after 15 seconds, use only when
necessary to conserve battery life.
Auto Power Off
• If the meter is not used for 15 minutes, the meter will turn
itself off to conserve battery life.
• To turn the meter back on after auto off, press “FUNC”.
• To disable auto power off, hold “FUNC” while turning the
meter on.
Measurement Preparation
• Make sure that when measuring current, the current
being measured does not exceed the maximum rated
current. This can cause overheating and damage the
meter.
• When measuring in manual range and the value to be
measured is unknown, start in the highest range and
adjust the range as needed.
• Make sure to turn the rotary switch to the proper position
before connecting the leads to a circuit.
• When connecting to a circuit, connect the black lead
(COM jack) first before connecting the red lead (INPUT
jack). Remove the leads in the opposite order when
finished.
